Mercury as Triplicity Lord
Getting the description right comes before deciding what to do about it. Handoffs where information drops out are the weak point, so write down what was agreed aloud and send it back to the other side.
In detail
In a night chart the air triplicity hands its rulership to Mercury, so this form requires the natal Sun in an air sign together with a nocturnal birth; it is carried from birth and does not lapse. Mercury signifies language, calculation, information and exchange. Held at the triplicity rung the effect is not one smooth conversation but a durable capacity for conversion: turning facts, prices and conditions into comparable form before deciding. Air by day belongs to Saturn instead, which is why two air charts of opposite sect read very differently.
FAQ
- Why does the air triplicity have two different lords?
- Because triplicity rulership is assigned by sect. Air belongs to Saturn by day and to Mercury by night, which means structure and endurance in one case and information handling in the other. Establish the sect of the chart before naming the lord.
